Early versions resolve <hostname>.<tag>.dc.oob.s4yhii.com via DNS to beacon the victim's hostname. Later versions run `node index.js` from a preinstall hook, which loads a bundled native addon (prebuilds/<platform>-<arch>/metrics.node, Linux and Windows builds). The addon forks a detached process that collects hostname, username, OS/arch, cwd and the full values of CI/cloud secrets from environment variables (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, SYSTEM_ACCESSTOKEN, AZURE_DEVOPS_EXT_PAT and others) and sends them as JSON via HTTP POST /native to oob.s4yhii.com:9999.\n\n---\n_-= Per source details.

The native binary reads a curated list of CI/cloud credential environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AZURE_DEVOPS_EXT_PAT, and similar), together with hostname, user, OS/arch, and cwd (gethostname/getpwuid/uname/getcwd on Linux; GetUserNameA/GetComputerNameA/GetCurrentDirectoryA on Windows). The collected values are serialized as a JSON body (`{\"src\":\"native\",\"pkg\":...,\"e\":{...}}`) and sent via a raw TCP socket as `POST /native HTTP/1.0` to the hardcoded host oob.s4yhii.com. The exported NestJS surface (forRoot/createLogger) is empty stub code with no real functionality, and a nested manifest at src/archetype/package.json contains the self-identifying marker `s4yhii-poc-2026-10-09` and contact `jesusitpro22@gmail.com`, matching the exfil host. The harmful code path fires automatically on `npm install` via preinstall and again on any require() of the package.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:05.9022827+00:00","affected":[{"ecosystem":"npm","name":"@galicia-toolkit-nestjs-20-lite/paas","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["1.0.20","1.0.24","1.0.21","1.0.22"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/paas/v/1.0.20","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/paas/v/1.0.24","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/paas/v/1.0.21","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/paas/v/1.0.22","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/paas"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17730","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17730","identifiers":["MAL-2026-17730"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
